How to discard corrupted frames in FFMPEG

Question

I’m running a command on FFMPEG that uses as input a video stream (A boroscope IP stream) and transforming it into a video file format. avi.

To do this I circled the following command:

ffmpeg -i tcp://192.168.10.123:7060 -c:v copy out.mov 

However, when running this command, some frames presented the following errors:

Even with these errors, the video was encoded.

The problem is that some frames are with a strange quality problem, probably because of these errors:

I’m not aiming to solve this problem, actually what I really want is to simply discard these frames through some parameter of FFMPEG itself, since the frames with good quality are already enough for what I need.

Continuing, I tried too, rather than transferring the input stream file to a video one. avi, turn it into a set of frames, through the command:

ffmpeg -i tcp://192.168.10.123:7060 "select='eq(pict_type,PICT_TYPE_I)'" -vsync vfr teste%04d.png

And, through this command, I was able to verify that the errors were directly connected to the frames with quality problems.

Also, I also ran a command that theoretically would discard the corrupted frames from the input (at least that’s what I thought this command would do):

ffmpeg -err_detect bitstream -err_detect buffer -err_detect explode -err_detect aggressive -fflags discardcorrupt -i tcp://192.168.10.123:7060 -r 1 -an -f image2  snapshot-%03d.jpg

But this command also did not work.

This is the first time I use FFMPEG, so I do not know very well the framework and its commands, my knowledge is really very shallow.

So finally, I wanted to know if there is any FFMPEG parameter that will REALLY discard all the frames that have ANY type of error at the time of encoding or removing the frames, so that there are no such quality problems.

Thank you very much!
